Product Overview
Motorola MC14094BCP - an 8-stage shift/store register with three-state outputs, packaged in a 16-pin plastic DIP. Part of the 4000/14000 CMOS logic family. Accepts serial data input, shifts through 8 stages, and outputs all 8 bits in parallel. Internal latches hold data independent of shift register state. Three-state outputs allow the device to be disconnected from the bus (high-impedance state) when not active, making it suitable for shared-bus and multiplexed designs. Operates on a DC supply of 3V to 18V. Pin-for-pin compatible with CD4094B.
Key Features
- 8-bit serial-in, parallel-out (SIPO) shift register with internal storage latches
- Three-state outputs: active high, active low, or high-impedance
- CMOS logic family - wide supply voltage range: 3V to 18V
- PDIP-16 package (through-hole, 0.1" pin spacing)
- Pin-for-pin compatible with CD4094B and HEF4094B
- Inputs: clock, data, strobe, output enable
- Unused inputs must be tied to VSS or VDD - not confirmed for specific application layouts, verify against datasheet before use
Applications
- LED display drivers and segment multiplexing
- Serial-to-parallel data conversion in microcontroller designs
- Shared-bus output expansion using three-state control
- Signal conditioning and waveform generation circuits
- Repair and replacement in legacy equipment using 4000-series CMOS logic
- Breadboard prototyping and hobbyist digital circuit experiments
Frequently Asked Questions
Is this compatible with CD4094B?
Yes. The MC14094BCP is pin-for-pin compatible with the CD4094B (Texas Instruments) and HEF4094B (NXP). They are functionally equivalent and interchangeable in most designs.
What package is this? Will it fit a standard DIP socket?
PDIP-16 - a 16-pin plastic dual in-line package with standard 0.1" (2.54mm) pin spacing. Fits any 16-pin DIP socket or breadboard. All pins on this unit are straight and ready to seat.
What power supply does it require?
DC supply voltage between 3V and 18V. Standard CMOS operating range - compatible with 5V TTL systems and a wide range of microcontroller supply rails.
Is a datasheet included?
Not included.
Does unused input handling matter for my circuit?
Yes. Any unused inputs must be tied to VSS (logic low) or VDD (logic high). Floating inputs can cause unpredictable output behavior. Unused outputs should be left open. Verify your specific layout against the datasheet before use.
CMOS logic from the Motorola era - date code on the body, pins ready to seat, three-state outputs waiting for their next bus. Wherever it lands on your board, it will do exactly what it was designed to do.
